So tested phosphate 0.1ppm range, ok fine... tested nitrate... and the water does not change color. 3 separate times I did the test, the last one with the refill kit I just got, and still no color change at all. And I have a really hard time believing my nitrate is 0 considering I don't dose carbon, i don't have any chaeto (I mean sure some algae grows on the side of the lagoon but this is a thin film not thick mat), the only filtration is a protein skimmer, and I feed primarily flake fish food.
I mean is there any way that nitrates can actually be 0 if phosphates are especially considering I don't actively do anything to try and reduce nitrate.
